9. External interface
I
2C: 100kHz mode is supported. The slave address can be selected using the pin settings.
Slave address: 0x98, 0x9A
1) Control specifications
Slave operations in the standard mode (100kHz) are supported.
These must be used for setting the internal registers and setting the internal status output and
γ correction
characteristics. The slave addresses are listed in the table below. Two addresses can be selected using the I
2CSEL pin.
Slave address:
(I
2CSEL=0)
Slave address:
(I
2CSEL=1)
2) Control and timing specifications
(1) Receive mode
As shown below, the slave address W, sub-address and input data must be set in this sequence after the start
condition. The data of each sub-address can be input in auto address increments consecutively from the data of the
sub-address specified. The data must be set consecutively with ACK between one data and the next. The stop
condition must be set last.
